As an important part of the automobile's appearance, automotive lamps often need to achieve interaction between the vehicle and the driver, as well as meet aesthetic requirements.

[0048] Example 1:

[0049] As Figures 1 to 5 shown, this embodiment provides a holographic display automotive lamp, including: a reflector 1, a first light source module 2, at least one half-transmissive and half-reflective member 3, and at least one second light source module 4; the reflector 1 and at least one half-transmissive and half-reflective member 3 are arranged in sequence along the light-emitting direction, the first light source module 2 is correspondingly arranged with the reflector 1, and the second light source module 4 is arranged in one-to-one correspondence with the half-transmissive and half-reflective member 3; the pattern lit by the first light source module 2 forms a projection pattern after being reflected by the reflector 1, the pattern lit by the second light source module 4 forms a projection pattern after being reflected by the half-transmissive and half-reflective member 3, and the projection patterns formed by the first light source module 2 and the second light source module 4 are spatially superimposed.

[0050] The reflector 1 and the half-transmissive and half-reflective member 3 are inclined reflector plates, the reflector plates are transparent members coated with a metal coating, and the metal coating is used for reflecting light.

The lamp cover 10 is a transparent structure or a smoked color structure.

[0051] In this embodiment, both the semi-transmissive and semi-reflective element 3 and the second light source module 4 are provided as one. After the pattern lit by the first light source module 2 is reflected by the reflector 1, it passes through the semi-transmissive and semi-reflective element 3 along the light-emitting direction to form a projection pattern in the projection area; the pattern lit by the second light source module 4 forms a projection pattern in the projection area after being reflected by the semi-transmissive and semi-reflective element 3.

[0059] Example 4:

[0060] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0061] This embodiment provides a holographic display automotive lamp, which utilizes a multi-layer reflective optical system with an inclination angle to realize the spatial three-dimensional superposition of the lit pattern, thereby realizing the holographic display effect.

[0062] The lamp includes two light sources, namely the first light source module 2 and the second light source module 4. The first light source module 2 and the second light source module 4 are surface light sources, and the first light source module 2 and the second light source module 4 can light up patterns. The lamp also includes a reflector 1 and a semi-transmissive and semi-reflective member 3. The reflector 1 and the semi-transmissive and semi-reflective member 3 are transparent members coated with a thin metal coating, and the semi-transmissive and semi-reflective member 3 has a certain reflectivity and a certain transmittance. The lamp also includes a lamp housing 9 with an installation structure and a lamp shade 10. The lamp shade 10 can be transparent or smoked.

[0063] The pattern lit by the first light source module 2 is reflected by the reflector 1 and passes through the semi-transmissive and semi-reflective member 3, and a pattern that can be observed directly in front of the lamp can be formed. At the same time, the second light source module 4 lights up a pattern, which is reflected by the semi-transmissive and semi-reflective member 3, and a pattern that can be observed directly in front of the lamp can be formed. The two patterns are spatially superimposed to form a spatial three-dimensional holographic-like image.

[0064] As Figure 2 shown, it is the pattern shown by the first light source module 2 reflected and imaged by the reflector 1. The first light source module 2 realizes the dynamic display of the pattern zebra crossing by adjusting the LED lighting sequence. As Figure 3 shown, it is the pattern shown by the second light source module 4 reflected and imaged by the semi-transmissive and semi-reflective member 3. When observed directly in front of the lamp, it presents a dynamic three-dimensional display effect of a pedestrian crossing the road, and is often combined with a brake light as a human-vehicle interaction for automotive lamps.

[0065] The first light source module 2 and the second light source module 4 can adopt the method of densely arranging and directly emitting RGB LEDs to form a multi-color dynamic display. And pre-storing or implementing transmission is adopted to display different animations. And according to cost limitations, monochromatic LEDs, such as white or red, can be used on the front headlights or taillights; or other monochromatic lights can be used for intelligent interaction, welcome animations, etc. At the same time, according to different costs, the LED arrangement pitch can achieve different schemes from 1 mm to 5 mm.

[0066] The first light source module 2 and the second light source module 4 can use a light guide plate structure to form a fixed pattern through micro-structured patterns or leather patterns to realize the display of the fixed pattern. Or a uniform light-emitting surface is formed through a light guide plate or atomized light-emitting material, and then the fixed pattern is realized through the occlusion of a decorative ring or spraying black paint and laser engraving. Combining with the control of the LED lighting sequence, simple animations can be realized.

[0067] By imaging the first light source module 2 and the second light source module 4 on the corresponding reflector 1 and semi-transmissive and semi-reflective member 3, when observed directly in front of the lamp, the patterns are spatially superimposed to realize a three-dimensional holographic-like display.

[0068] The first light source module 2 and the second light source module 4 can be a light source module 11, as Figure 8As shown, the pattern can be displayed in two front and back regions, which are spatially superimposed on the reflector 1 and the semi-transmissive and semi-reflective member 3 respectively. The light source module 11 can be a direct arrangement display of LEDs (light-emitting diodes), or a fixed pattern formed by blocking a uniform surface light source.

[0069] As Figure 6 shown, by adding the second light source module 4 and the semi-transmissive and semi-reflective member 3, more than two patterns can be spatially superimposed to form a more complex three-dimensional pattern.

[0070] As Figure 5 shown, by using the solution of the light guide plate 5, the light source module can form a fixed pattern with lower cost. The LED light sources 7 are evenly distributed on one side of the light guide plate 5. The lower surface of the light guide plate 5 uses microstructures or leather grains and is lit into a fixed pattern when irradiated by the LED light sources 7. The light guide plate fixing bracket 6 is a white light guide plate bracket or an aluminized bracket.

[0071] In other embodiments, other structures can also be adopted. As Figure 7 shown, the light guide plate 5 is covered with microstructures or leather grains, and a homogeneous diffusion sheet 8 is also provided, and there is a pattern of spray painting and laser engraving on the outer surface.

[0072] The utility model utilizes a multi-layer reflective optical system with an inclination angle to realize the spatial three-dimensional superposition of the lit patterns, thereby realizing the holographic display effect.

[0073] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0074] The specific embodiments of the present utility model have been described above. It should be understood that the present utility model is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present utility model. Without conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.
